Last night I prepped a fossil that kept changing on me

I'm in the lab with a matrix block the size of a shoebox, and every time I turn away it's a different animal—first a theropod ankle, then a whale earbone, then something with no name. I keep saying 'easy, easy' like you'd soothe a horse, but the jackhammer in my hand is a chicken's beak. Woke up annoyed that I never got to see it finished. That's fieldwork for you, even in your sleep.
